Can the ice caps melt fast enough save Canada’s sea ports?
Chart Datum varies from country to country, but always follows some low water definition. In Canadian coastal waters, our present target threshold is Lower Low Water Large Tide (LLWLT). LLWLT is the lowest predictable tide *averaged* over an 18.6 year tidal epoch. […]

Apparently not.
As always, the rugs are being pulled from under the Prophets dumb feet 🙂
This just demonstrates that water is a non-renewable resourse, and that it is high time conservation measures and punative tax policies are put in place.
Proof! The only constant is change.
And many have too much time on their hands.= TG
ummmm maybe the land is rising.
ummmm maybe the land is rising.

or ummmmmmmmmmm maybe the land is falling, just not as fast as sea level.
Either way, the great fear campaign of flooded port cities can be discounted for what it always was.
Part of Great WARMonger Lie.
on a lighter note,
150,000+ motorcyclists take over Port Dover, Ont on Friday the 13th!

Anybody remember the old Gilligan’s Island episode where the professor thought the island was sinking. He had put a stick in the lagoon and everyday he would measure the water level by seeing how high the water was on the stick. Every day the water level was higher so the island had to be sinking. Actually Gilligan had been using the stick to keep track of where he had been fishing and had been moving the stick farther and farther out into the lagoon.
To be fair, causal attribution of changes in local sea level are not a trivial matter. There are four issues here, only one of which is the amount of free planetary water. The other three are the evolving shape of the planet, variations in the local gravitational field, and non-terrestrial effects.
There is a really cool applet that demonstrates elevation (geodic) change over time at http://icgem.gfz-potsdam.de/ICGEM/ICGEM.html
Watch it. Now you have something else to worry about 🙂
See the sidebar at http://www.space.com/scienceastronomy/gravity_map_030725.html for a gravity map.
Non-terrestrial effects are the various lunar, solar and planetary tides…
Simply put, amount of water, local elevation and gravitational strength determine local sea levels **on average**. The question of whether the “oceans are rising” is not exactly an easy one to answer.
Fred:
Are you seriously suggesting that the land is falling in Churchill?

Point taken Tenebris, but there are some simple proofs out there. Go visit http://www.john-daly.com/
where a picture of a datum mark in Tasmania shows very little if any change in water level over the period 1841-2004.
Sometimes we get caught up in the technological proof a-la IPCC at the expense of common sense and observed conditions.
So, had we been more patient, we could have saved a boondoggle of money on that PEI bridge.
The only truly finite, irreplacable resource is time. Tax that and slow its rate of consum[ption.
Very true Joe….only problem is nobody in the KyotoKult Kamp knows that the stick with the carrot is being constantly moved.
Reason is wasted on a generation conditioned to accept global fascism if it has a green wrapper.
According to the enviromentalists wackos when the polar icecaps melt earth will look like it did in the dumb movie WATERWORLD where KEVIN KOSNER looks like a complete dork AL GORE IS A LIAR
Canadian women will be mandated to wear burkas long before Florida has a high water problem.
The challenge before us is our freedom not our climate.
Have they ever heard of erosion or where the Archimedes Principle might fit in with all this crazy Goraceous, Suzkookie, Lizzie May Greenie bulls**t.
We’ll leave Dion off the list, he’s been at the Stampede in Calgary jumping cow-flops, telling unintelligible golf jokes, something about right, left and center. Poor guy, not at all comfortable, needed his sidekick Iggy who was nowhere in sight.
When floating ice melts to water, the water level doesn’t rise.Try putting ice cubes into a glass of water, when they melt the water level stays the same.
Ice occupies more space than water (ever had pipes crack in the fall when the water freezes)That’s why you see icebergs protruding the surface of the ocean, it reaches an equilibrium. when floating ice melts the portion below the surface uses less volume which is compensated for the exposed ice above the surface.
The last time I checked all arctic ice is floating.
So if all the Arctic ice melted the oceans wouldn’t rise.
The only ice that can raise sea level is ice that is presently on land and that is limited to Greenland and Antarctica and the last time I check thet Antarctic is getting cooler except for a very small peninsula.
On the peninsula the ice is calving (falling of the edge) not because of warming but because as snow and ice reach approximately 50 feet thick it becomes plastic and starts to flow and when it reaches the edge of the cliff it falls off.
If the Gorical was right the oceans should have risen a foot this year…don’t see much evidence of that.
RL: You’ve got it! Ice cubes in a glass of water explains it!
Do we need any more proof about the Gore, Suzuki Spoof, Sham, Scam?
The song goes “How high’s the water risin’ Mama”?
Well it ain’t!
Actually iggy, in NS we are still slowly rebounding from the weight of ice from the last ice age.
An IPCC report warned of a sea level rise of up to 59 centimetres over the next century. Think about that for a minute: The absolute worst-case scenario that the true-believing envirocultists of the IPCC can come up with is that if you stand with your toes in the ocean today, in one hundred years the water will be up to your knees. This is the doomsday scenario that they want spend trillions of dollars to try to avoid. You’d think that they could come up with a scarier version of Armageddon, using their phony computer models and all, but nope. A measly 59 cm sea level rise, maximum. Pathetic.
Putting global warming into perspective for just a second, Ontario used to be solid ice right down to almost Barrie only 15,000 years ago.
Call me crazy, but I like it the way it is now. Warmer is better.
tnx for the link Kate.
🙂
Phantom I always have this vision.
If Gore and Suzuki were alive when the ice was 1 mile thick over Winnipeg in the summer. They would turn the economy in to a massive effort to harvest every mammoth hide to cover the ice sheets to prevent them from melting.
Our high is 22 degrees here in the middle of the hottest month of the year.
If its 23 will I care? Plus their methods of measuring are fraudulent in many cases.
Speaking of mammoths, some guy recently found a whole baby one frozen in Siberia. They are going to have a go at sequencing its genome.
Maybe we can get some real mammoths again some day. Mmmm, mammoth steak!
Or will you care if a January night “warms” up to -25C instead of -26C ?? a hundred years from now.
“Try putting ice cubes into a glass of water, when they melt the water level stays the same.” It certainly works with my rum & coke. Actually, the level goes down but I think there are other influences at work here. More research his required. I’ll drunk to that.
It hits -25 in Kelowna????
ron its funny here in Winnipeg you can drive about 2 hours north maybe 3 before you run out of arable land if it gets colder we are toast if it gets warmer we’ll have to steal technology from North Dakota.
damm did that texas canuck take my drink?
phantom thats one time its hard to argue with cloning. Mammoth park,
most of Canada is rising due to isostatic rebound from the last iceage. the peace river is a great example where the river has eroded a very deep cut though constantly rising land.
most of greenland is below sealevel due to the weight of the ice, if it were to melt instantaneously like the Goracle says there would be a large fresh water lake surrounded by islands, say for a few years. it doesnt happen like that so greenland will be above the water by the time all the ice melts.
however, during the meanwhile we have to reverse the trend before we can get the 60ft that Dr. Bono Suzuki predicts.
why doesnt the MSM call these twits on something.
Been here only three years —– have already seen -27C. Twice.
Edge of arable land in MB ?? Yes. Been there done that — for 38 years 🙂
Global Warming of 1C by 2100 — N-Dakota ag tech.
2C by 2200 — SD
3C by 2300 — Nebraska
Canada would be an ag powerhouse !!
On the other hand —– Global Cooling, like in the 1700s, and Canada will starve. There is nobody north of us to copy.
Tim Ball has been saying this for years —– CBC won’t listen — too taken by a fruit fly 🙂
indicative of nothing except a good round of golf and a cold beer. hah hah.
Job ONE! IPCC take note!
Supply clean coal tech, [foreign aid], for hundreds of thousands of *dirty* coal-gen plants across the globe. Mainlly India, China and the USA. USA power is 50% coal generated.
Promote moving away from burning petroleum or bio fuels for trans port and campaign for the use of compressed air and battery-pack motor power.
Start referring to the problem we all face as *World Pollution* and drop the *Warming* diversion.
Clarify and simplify the message. You are drowning your audience in seas of detail.
Get all IPCC Egos together and simplify or lose the exercise completely. = TG
The biggist amount of HOT AIR come from the mouths of AL GORE,DAVID SUZUKI and JAMES LOVELOCK
